jaguar x-type Gearbox Fault and Gear kick

May 2010 I purchased a 2002 Jaguar x-type 2.5 automatic with 83000 miles, driving the car off the lot, everything was in order and working perfectly. Roughly 2 weeks after driving the car I noticed when placing the car into manual gears it was as if the gears were all off and could not find the 2nd and 3rd gears on the J box. This was the first problem after this I noticed that the check engine light came on along with the gearbox fault light, placing the car into safe mode and only letting the car drive in fourth gear, this was the second problem. After letting the car sit for a wile the light would go off and everything went back to normal, soon after the same problem occurred. Now when driving the car the light always comes on and the car Jerks and kicks when shifting into second and third gear. The weird thing is the jerking and kicking does not happen every time so shifting occurs normally, I would say its about fifty/firty. Can someone please help me, I am really concerned that it may be my trans, but wondering if it may just be the j box.

Tranny Doomed

Be prepared for your transmission to quit any day now, this is exactly what these cars from that vintage do when the tranny is about to die. Check into your state's warranty for used cars from dealer or private party, and definitely have the car looked at. Unfortunately the transmission is a closed system and has to be completely replaced upon catastrophic failure. When the transmission goes, it won't be able to find 2nd or 3rd gear at all, and will always slip back down to 1st. Good luck and sorry about your misfortune.

A possible solution to limp mode

I have an x-type 3.0 sport auto trans with Gearbox Light on myself. To get it out of limp mode I found that a solenoid connected to the brake pedal was dangling. I guess my feet must have kicked it loose... After reconnecting it, it drove better. I think the Gearbox Fault light has something to do with the car understanding what gear the car is in. The light comes back on after reaching about 55mph for a while, but at least its not in limp mode anymore. Once the light comes on, amazingly the car seems more sure of what gear its in. Go figure. I still need to check my codes, but it can get kinda pricey. The car been driving fine (been over 8000 miles since reconnecting the solenoid cable near foot brake), minus the annoying Gearbox Fault light, so I'm in the habbit of pressing that RESET button to get rid of message... At least until I find a a machine that actually understands Jaguar x-type codes, lol-

Gearbox fault X Type Jaguar

A large number of X Type Jaguars with auto transmission manufactured after 2004
were recalled for a cruise control fault. At this time my jaguar has a fault code relating to the egv valve. This is going to be replaced next Friday at a cost of 380 GBP.
will update in 2 weeks

X-Men get your Transmission and Differential serviced. I had the same issue until I had them properly serviced -the flush on these cars requires it be hook up to a system that power flushes the transmission -continual flow. Cost was $250 and included 12 quarts of SYN ATF plus the ATF KIT-N. The Differential flush was $150 and included 75W-140 REDLINE. I did the tranny first and two-weeks later did the diff -- what a world of difference.

I purchsed my 2002 Type (Auto) with 83K on it and it now has 116K and I no longer have that problem. The other culprit with respect to the Engine-Drive Train light are the front Wheel Hubs. As they degrade the 4WDR system electronics begin to detect faults causing the system to go into "safe-mode". Replacing both front Hubs next week.

A big thank you to Mark at Nottingham JAGTEC because now my car has these problems resolved.

Conclusions after internet search.
I believe the software programmer had a limited amount of space to prepare the car owner for possibly an expensive
repair. Inform them of the importance of immediate mechanical attention.
And choose the wording we all now know "GEARBOX FAULT."

It could have read

"Your car has developed a fault which may or may not be serious.
You are advised that this requires mechanical attention as delay may further damage you car.
One of the many sensors fitted to your car has given an unexpected reading.
This might be faulty sensors. A bad / damp or corroded connector to a sensor or ecm unit.
Your fault code will have been stored.
Reading these codes and correcting these faults is now your only option.
Do not forget to clear all stored codes."

Similar problem

Hello I have an automatic transmission 2004 x-type(3.0), and recently went thorough some rough times with it. It all started in this sequence: 1. One day as I was driving on the highway apx 70mph, the car just decided to stay in one gear, I think it was 4th as the rpms were a little high. So I pulled over and the car wouldn't downshift. After 2hours it went back to normal. 2. Then about two weeks later I noticed that the car couldn't go past 3,000 rpms, it would start jerking as if trying to grab the gear but slipping. This problem would some days be there but some days go away. 3. Next came the first brake down. I was driving to work and all of a sudden it just went to neutral, but in the sense that no gears worked nor the reverse and even when shifted in to park it would make a grinding sound then catch the teeth. 4. Getting some advice, I had switched the transmission with another used one (witch came with a new torque converter). That was a fail because it went through the same sequence as the first one, first the slipping of gears then totally braking down.As additional info I should mention that I had checked the code and it gave me a knock sensor check engine code. I'm sorry if I'm posting this incorrectly but I'm new and I'm trying to dig into this complicated but rather nice car that I have. Hope that maybe someone could use this as an example of what not to do and explain to me and others how I could have prevented such a mess.

There was likely nothing wrong with your original transmission. I have learned that this problem is with the J-Gate Assembly. I just had mine RESET this past Friday and although it occurred a few more times since the work was done its apparent the problem is with the sensors and or transmission cable linkage and the selector switch. I've driven the car more since Friday and it has yet to reoccur; in fact when it did happen the few times after being RESET, the transmission retained its speed and only the POWER-TRAIN MALFUNCTION indicator came on. I have attached the Technical Service Bulletin that speaks to the adjustment procedure. At minimum you'll need to have the J-Gate RESET and the linkage cleaned -- the cable could possibly need replacing -- I just had mine cleaned and RESET. The worst case is you will need to replace the J-Gate Assembly.

Similar problem - solved...

I've read the other posts following this - it does appear that the gearbox failed lamp covers a multitude of issues, some more serious than others.

My 2002 petrol auto X-Type has for some time suffered from what my repairer calls "torque convertor chatter" and has had instances of being reluctant to change gear or, alternatively, be over enthusiastic to change down, then changing its mind and changing back again. Usually on long highway hills.

Then a while ago after a very gentle 100 mile drive (slow highway, never more than 60 mph, the gearbox light came on and the thing stuck in 4th gear.

This happened more and more frequently - it could be cleared by a key-out re-start. On some occasions it occurred within 3 miles of home when starting from cold.

A gearbox specialist (E.J. Rose of Mansfield - who specialises in Jaguar gearboxes) said that there was nothing wrong with the box - being a really nice guy he didn't charge me for this guidance!

Eventually my repairer (who maintains the LPG installation on the car) found an intermittent wiring short in the loom somewhere below the battery tray. There is a lot of loom there and it took many hours to find it let alone put things back again - but problem solved and "torque convertor chatter" also much improved. The problem had probably been building for >30k miles.

Congratulations to AJ's of Chesterfield for finding this and fixing it!

The fault code was always the same - gearbox rear solenoid overheating - but that solenoid is not anywhere hot and was working just fine - I cannot point you to which part of the loom was causing the rubbing, or how it got into that condition.

Regards

Ian
